An anonymous reader writes "Brooks Davis has announced that the FreeBSD Project has now officially switched to Clang/LLVM as C/C++ compiler. This follows several years of preparation, feeding back improvements to the Clang and LLVM source code bases, and nightly builds of FreeBSD using LLVM over two years. Future snapshots and all major FreeBSD releases will ship compiled with LLVM by default!"
An anonymous reader writes "OpenBSD 5.2 has been released and is available for download. One of the most significant changes in this release is the replacement of the user-level uthreads by kernel-level rthreads, allowing multithreaded programs to utilize multiple CPUs/cores."
An anonymous reader writes "ACM Queue interviews Cambridge researcher (and FreeBSD developer) Robert Watson on why processor designs need to change in order to better support security features like Capsicum — and how they change all the time (RISC, GPUs, etc). He also talks about the challenge of building a research team at Cambridge that could actually work with all levels of the stack: CPU design, operating systems, compilers, applications, and formal methods. The DARPA-sponsored SRI and Cambridge CTSRD project is building a new open source processor that can support orders of magnitude greater sandboxing than current designs."

New submitter Madwand sends this quote from the NetBSD Project's announcement that NetBSD 6.0 has been released:
"Changes from the previous release include scalability improvements on multi-core systems, many new and updated device drivers, Xen and MIPS port improvements, and brand new features such as a new packet filter. Some NetBSD 6.0 highlights are: support for thread-local storage (TLS), Logical Volume Manager (LVM) functionality, rewritten disk quota subsystem, new subsystems to handle flash devices and NAND controllers, an experimental CHFS file system designed for flash devices, support for Multiprotocol Label Switching (MPLS) protocol, and more. This release also introduces NPF — a new packet filter, designed with multi-core systems in mind, which can do TCP/IP traffic filtering, stateful inspection, and network address translation (NAT)."

With the goal of bringing more experimental development to the OpenBSD
code base, a few developers have announced a fork named
Bitrig. According to their FAQ, Bitrig aims to build a small system
targeting only modern hardware and "be a very commercially friendly code base by using non-viral licenses where possible." Their first step toward that goal was removing GCC in favor of LLVM/Clang. The project roadmap shows their future goals as adding FUSE support, improving multiprocessing, porting the system to ARM, and replacing the GNU C++ library with LLVM's.

An anonymous reader writes "Shared in last quarter's FreeBSD status report are developer plans to have LLVM/Clang become the default compiler and to deprecate GCC. Clang can now build most packages and suit well for their BSD needs. They also plan to have a full BSD-licensed C++11 stack in FreeBSD 10."
Says the article, too: "Some vendors have also been playing around with the idea of using Clang to build the Linux kernel (it's possible to do with certain kernel configurations, patches, and other headaches)."

An anonymous reader writes "MINIX 3.2.0 was released today (alternative announcement). Lots of code has been pulled in from NetBSD, replacing libc, much of the userspace and the bootloader. This should allow much more software to be ported easily (using the pkgsrc infrastructure which was previously adopted) while retaining the microkernel architecture. Also Clang is now used as a default compiler and ELF as the default binary format, which should allow MINIX to be ported to other architectures in the near future (in fact, they are currently looking to hire someone with embedded systems experience to port MINIX to ARM). A live CD is available."
The big highlight is the new NetBSD based userland — it replaces the incredibly old fashioned and limited Minix userland. There's even experimental SMP support. Topping it all off, the project switched over to git which would make getting involved in development a bit easier for the casual hacker.
An anonymous reader writes with word of the release earlier this week, after eight months of development, of DragonFly BSD 3.0. The release includes improved scalability through finer-grained locking, improvements to the HAMMER file system in low-memory configurations, and a TrueCrypt-compatible disk encryption system. DragonFly is an installable system, but it can also be run live from CD, DVD, or USB key.
An anonymous reader writes "Communications of the ACM is carrying twoarticles promoting the Capsicum security model developed by Robert Watson (FreeBSD — Cambridge) and Ben Laurie (Apache/OpenSSL, ChromeOS — Google) for thin-client operating systems such as ChromeOS. They demonstrate how Chrome web browser sandboxing using Capsicum is not only stronger, but also requires only 100 lines of code, vs 22,000 lines of code on Windows! FreeBSD 9.0 shipped with experimental Capsicum support, OpenBSD has patches, and Google has developed a Linux prototype." While the ACM's stories are both paywalled, the Capsicum project itself has quite a bit of information online in the form of various papers and a video, as well as links to (BSD-licensed) code and to various subprojects.

ReeceTarbert writes "VirtualBSD 9.0 is a desktop-ready FreeBSD 9.0-RELEASE built around the XFCE Desktop Environment for good aesthetics and usability, and is distributed as a VMware appliance (that can also be made to work with VirtualBox) so even non techies can be up and running in minutes. The most common applications, plugins and multimedia codecs are ready since the first boot and chances are that you'll find VirtualBSD very functional right out of the box. However, it should be noted that VirtualBSD is more a technology demonstrator than a fully fledged distribution, therefore is squarely aimed at people that heard about FreeBSD but have never tried it, didn't have enough time
to build the system from scratch, or have since moved to a different OS but still need their FreeBSD fix from time to time."

PuceBaboon writes "It's worth noting that, in addition to the main FreeBSD release covered here recently, PC-BSD has also released their 'Isotope' edition, based on FreeBSD 9.0. Why would you be interested? Well, PC-BSD, while not the first, is certainly the most current version of FreeBSD aimed squarely at the desktop user. Pre-configured for the desktop and using a graphical installer, the 9.0 release includes KDE, GNOME, XFCE and LXDE desktop environments, an update manager, WiFi 'quick connect,' BootCamp support and auto-configuration for most common hardware. Live-CD, VirtualBox and VMware release images for 32- and 64-bit architectures also make it easier than ever for users to test the release before committing to a full install. Check out the torrents (scroll down), main download page and the PC-BSD 9.0 manual pages."

A few highlights include: A new installer, bsdinstall(8) has been added and is the installer used by the ISO images provided as part of this release, The Fast Filesystem now supports softupdates journaling, and Kernel support for Capsicum Capability Mode, an experimental set of features for sandboxing support."
